Given numbers are 660,161,247,702

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 660,161,247,702 is 236215980.

Find LCM of 660,161,247,702 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 13 x 110 x 161 x 19 x 9 = 236215980

Therefore, the lowest common multiple of 660,161,247,702 is 236215980.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

660 x 161 x 247 x 702 = 18424846440

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

161 : 1, 7, 23, 161

247 : 1, 13, 19, 247

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,161,247,702, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

161:7x 23

247:13x 19

702:2x 3x 3x 3x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 13 = 78

Therefore, the value for common factors is 78.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 18424846440/(1x78)

LCM = 18424846440/78

LCM = 236215980

Thus, we can understand that the LCM of 660,161,247,702 is 236215980.
